“Vatican Zero Day”: The Church in the Era of Artificial Intelligence and Hybrid Warfare
Luigi Ricci’s new essay analyzes the Vatican’s vulnerabilities amidst AI, disinformation, narrative manipulation, and global conflicts.
Available in bookstores from May 8th, published by Lindau Editore.
ROME, May 7, 2026 – It has no armies, no borders, and leaves no obvious traces. Yet, it is already underway. It is the hybrid warfare of the 21st century: a conflict no longer fought solely with conventional weapons, but through data, algorithms, disinformation campaigns, public opinion manipulation, and the control of narratives.
This is the starting point for “Vatican Zero Day: Hybrid Warfare and New Threats to the Church in the Era of Artificial Intelligence,” the new essay by Luigi Ricci, statistician, complex systems analyst, author, and director of Barometro, available in bookstores starting May 8th from Lindau Editore.
The book explores the vulnerabilities currently facing the Catholic Church in a landscape dominated by AI, algorithmic polarization, and new forms of geopolitical pressure. Cyberattacks, deepfakes, narrative manipulation, and cognitive conflicts have become tools of a silent war that aims not necessarily at physical destruction, but at the progressive erosion of symbolic and spiritual authority.
In this scenario, Ricci views the Vatican not only as a religious center but as one of the few global institutions still capable of proposing a vision of humanity that cannot be reduced to data, performance, or function.
“Today, it is no longer just infrastructure or borders that are under attack, but consciences,” explains Luigi Ricci. “The true war of our time is narrative: it is fought over the meaning of things.”
The title refers to the computing concept of a “Zero Day”, an unknown vulnerability that can be exploited without warning. Ricci transfers this paradigm from cybersecurity to the cultural, spiritual, and anthropological fields: the deepest fragility concerns not just digital systems, but the ability of institutions to resist the manipulation of reality.
The volume highlights the Vatican’s role as a “semantic power” in a world where controlling narratives and attention has become central to contemporary geopolitical balances.
Among the core concepts of the book is the “Gospel of the Algorithm,” a new form of symbolic power where technology, markets, and cultural influence intertwine to propose alternative models of meaning, belonging, and even salvation. Large digital platforms are no longer just tools, but environments capable of shaping behaviors, desires, and visions of the future.
“If reality can be rewritten by an algorithm, even the sacred becomes vulnerable,” Ricci continues. “The risk is not only technological; it is anthropological. It concerns how human beings perceive themselves, their freedom, and their relationship with the world.”
Alongside the analysis of threats, the book identifies potential paths for a response. Among these are the “Digital Ronin”: figures from the tech world who are beginning to question the limits of innovation, the responsibility of algorithms, and the need to preserve an authentically human space within the digital ecosystem.
With an analytical and visionary style, “Vatican Zero Day” offers an original interpretation of the present. It is not a reassuring text, but a cultural alarm: the battle of our time is not just about technological dominance, but about the defense of humanity in an era where even conscience can become a battlefield.
